I can't think of what pin they could be referring to that has to slide freely... Only think that slides freely would be the piston itself which is inside the caliper and that doesn't get greased. The caliper is held on with 2 bolts to the carrier. The pads are held in place with a clip... No sliding anywhere, it isn't a floating caliper. :-?
I'll check my manual when I get home later.
